Objective: To evaluate the influence of supplementation with retinyl palmitate in the immediate postpartum period on the levels of secretory immunoglobulin A (SIgA) in colostrum.
Methods: A clinical trial was conducted among 96 recently-delivered mothers treated at a public maternity hospital, divided into control group, which was not supplemented (n = 44), and test group, supplemented on the first day postpartum (n = 52). Samples of 2 mL of colostrum were collected on the first 2 days postpartum.
Objective: To assess the levels of alpha-tocopherol in human colostrum following supplementation with capsules containing vitamin A plus synthetic vitamin E.
Methods: Thirty healthy women about to give birth were recruited from a public maternity hospital. After overnight fasting, blood samples as well as colostrum samples (2 mL) were collected.
Vitamin A is particularly important during the critical periods of growth, proliferation and development of tissues such as pregnancy, neonatal period and childhood. This study aims to evaluate the influence of maternal variables such as gestational age and parity, on the levels of retinol in colostrum and verify that the concentration of vitamin A in the colostrum of those mothers provides the recommended amount of this micronutrient for newborns. We recruited 84 healthy pregnant women attended at a Brazilian public hospital.

Methods: Thirty healthy childbearing women were recruited in a public maternity hospital, and samples of blood, fasting colostrum, and postprandial colostrum were collected from them up to 12 hours after delivery.
Results: The serum alpha-tocopherol concentration was 1,939.
